Home depot is selling natural-gas powered home electric generators (7 kw and larger). The price for a 7 kw system is $3000 (I think it's a turn-key system). This works out to a constant 120v/50 amp (240 v, 25 amp) supply.
If I'm comparing the cost of electricity (in cents per kwh) vs the cost of natural gas (in terms of cents per cubic meter or cubic foot) does anyone know the break-even ratio that would make it economical to generate most (or all) the electricity for your house from your natural gas supply using one of these units?
What about natural-gas-driven AC compressors? Wouldn't that be a smart choice to run your AC compressor on natural gas in the summer (when NG demand is low) ?
